This cheat combination was disabled in final release, but probably was planned to be enabled. There is should be combination Up, Down, Down, Right, Left, Right, Right, Left, Up, Down, Down, Right, but on development stage was shorted to first two buttons. Because some key press check, pressed buttons not wait too long, key check code looks kinda fixed, so it need more fixes to work properly, but rapid pressing of buttons is work fine for me.

(BUR) GameGenie:
Absolutely all games by Codemasters have internal PRG ROM and CHR RAM testing routines. They called "Smiley tests". Tests are normally enabled, but for triggering it needs pressing all D-pad buttons. For performing PRG ROM test it needs to hold Up + Down + Left + Right + A + Select + Start. For performing CHR RAM test it needs to hold Up + Down + Left + Right + B + Select + Start. Without controller modification it is impossible. GameGenie codes allows you to do not use D-pad buttons for triggering cheat, only A + Select + Start and B + Select + Start. But it affects on ROM's CRC. I ran these tests normally by cheating with debugger, so I wrote normal CRC tests results in brackets.

Dizzy The Adventurer

(BUR) GameGenie:
Absolutely all games by Codemasters have internal PRG ROM and CHR RAM testing routines. They called "Smiley tests". Tests are normally enabled, but for triggering it needs pressing all D-pad buttons. For performing PRG ROM test it needs to hold Up + Down + Left + Right + A + Select + Start. For performing CHR RAM test it needs to hold Up + Down + Left + Right + B + Select + Start. Without controller modification it is impossible. GameGenie codes allows you to do not use D-pad buttons for triggering cheat, only A + Select + Start and B + Select + Start. But it affects on ROM's CRC. I ran these tests normally by cheating with debugger, so I wrote normal CRC tests results in brackets.

(BUR) Hidden text:
RESET routine in this game uses string "D.BUSTER" to check if game was soft or hard reset. Also game contains some hidden copyright text at the end of the ROM: "HARUHISA.UDAGAWA & KUMI.HANAOKA". This text is a part of the hidden CRC test routine and used in some other games programmed by the same people, but in this game this sting doesn't used as test data.

(BUR) GameGenie:
GAUYNTEI-At reset, game performs some manipulations with expansion port sending and reading some data sequence to it then compare resulting data with original. Probably there is some special device for testing purposes only. With this code you may pass device checking and see CRC test itself. If data matches, game performs partial (one from each 15 bytes) data CRC tests. While checking PRG data, display color is red, and if check fails display will remain red and game stops. While checking CHR data, display color is green and if check fails display will be flashing from red to green infinitely. GoodNES version ROM pass these tests normally.

Dragon Fighter

(BUR) GameGenie:
ZEVEUSLE-Enable "obj test mode" instead "sound test mode".
Previously game has another cheat handling routine. This routine was disabled at all in the release version. There were another "obj test mode" along with "sound test mode" cheats. They was accessible only after cheat mode enabling, used in the level selecting cheat. After that "obj test mode" might be triggred by pressing B + Select + Start on first controller, "sound test mode" - by pressing A + Select + Start. In the final release "obj test mode" was disabled and "sound test mode" was moved to simplier cheat combination.

ZKVPENUY-This GG code enables development stage funny debug feature. There is some memory area that contain some critical game variables. For some reason the game calculates simple checkum for this area and then compare it with previously calculated value. In final release wrong CRC cause to rewriting some wars with default values. But there was message "You got a checksum error today, but that doesn't mean you have to like it!" that appears when CRC is wrong and then jump to the game ending. Seems this stuff was made to prevent from cheating for level select or some other parameters.

There is some old cheat left in final version. When title appears from bottom of screen and before it stop scrolling you must press Up, Right, Down, Left, Down, Right, Up, Left, A, B sequence and then press A to increase some internal counter up to 99. There is no so much time to enter cheat and increase counter at the title screen rolls. In final version memory areas for storing key sequence and for checking this sequence is different so it isn't possible to trigger cheat. Anyway, cheat counter don't reading at all in game, so it absolutely unuseful. It may be used as default round time counter. 0x50, 0x51 vars are counter in decimal notation, 0x4F main cheat flag, 0x53-0x5C sequence check area, 0x52 - sequence length variable. 0xAD-0xB6 - sequence store area, 0xAC - sequence length var (uninitialized by default, may be any index in zero memory).

US version:

(BUR) GameGenie:
Absolutely all games by Codemasters have internal PRG ROM and CHR RAM testing routines. They called "Smiley tests". Tests are normally enabled, but for triggering it needs pressing all D-pad buttons. For performing PRG ROM test it needs to hold Up + Down + Left + Right + A + Select + Start. For performing CHR RAM test it needs to hold Up + Down + Left + Right + B + Select + Start. Without controller modification it is impossible. GameGenie codes allows you to do not use D-pad buttons for triggering cheat, only A + Select + Start and B + Select + Start. But it affects on ROM's CRC. I ran these tests normally by cheating with debugger, so I wrote normal CRC tests results in brackets.

This text is a part of a hidden CRC test routine and used in some other games programmed by the same people, in this game this string partially used as test data.

(BUR) GameGenie:
GAXYNTEI-At reset game performs some manipulations with expansion port sending and reading some data sequence to it then compare resulting data with original. Probably there is some special device for testing purposes only. With this code you may pass device checking and see CRC test itself. If data matches, game performs partial (one from each 15 bytes) data CRC tests. While checking PRG data display color is red and if check fails display will remain red and game stops. While checking CHR data display color is green and if check fails display will be flashing from red to green infinitely. GoodNES version ROM pass this check normally.

(BUR) GameGenie:
PASZSYAA-Normally, you can play this game alone, with computer or with another player. When you play with computer, it's name is always "ELECTRO" and its player number always 2. But game designed with another player controlled by computer with player number 1 in mind. It's name is "LI'L BIT" and it's always out of business. With this game genie code you can enable it as player 1 in two player mode with computer. In this mode two computers will play themselves, but second one will with empty name since game is not designed for two computer players.
GGOPPOLK+XPOPZOOO-There was some test screen called "DEMONSTRATION SCREEN" in earlier versions. With this code you can enter it instead of copyrights screen. This screen wait three times longer than copyrights screen before ends and can be skipped by pressing any button.
UEEOKZXA+YENPVXKX+XKKPEXVV-This code enables additional "TIMER" string with previously disabled counter. All code exists in ROM but haven't links between additional code parts.
AXXOSOSA+PXXOVOUS+VXXONPZE-This code re-enables additional string on copyright screen with development date: "20TH SEPTEMBER, 1989.". Seems it was planned to release in Japan in 1989 year, but cancelled.

For performing PRG ROM test it needs to hold Up + Down + Left + Right + A + Select + Start. For performing CHR RAM test it needs to hold Up + Down + Left + Right + B + Select + Start. Without controller modification it is impossible. GameGenie codes allows you to do not use D-pad buttons for triggering cheat, only A + Select + Start and B + Select + Start. But it affects on ROM's CRC. I ran these tests normally by cheating with debugger, so I wrote normal CRC tests results in brackets.

Meaning of pressing Up + B + Select combination before resetting console to enable this secret message. But in final release there is no pad reading routines called from RESET routine before cheat code check. So only way to enable it in final release this GG code.

This text is a part of hidden CRC test routine and used in some other games programmed by the same people, in this game it used as one of the test data.

(BUR) GameGenie:
GANYNTEI-At reset game performs some manipulations with expansion port sending and reading some data sequence to it then compare resulting data with original. Probably there is some special device for testing purposes only. With this code you may pass device checking and see CRC test itself. If data matches, game performs partial (one from each 15 bytes) data CRC tests. While checking PRG data display color is red and if check fails display will remain red and game stops. While checking CHR data display color is green and if check fails display will be flashing from red to green infinitely. GoodNES version ROM pass this check normally.

(BUR) GameGenie:
GEOKYAAX-Engine test mode. Reset the game, then you can scroll backgroung in any direction with first controller, move test sprites and write sting "TEST123456789TEST" to the backgroung with second controller buttons. Buttons A and B on first controller play some test sounds.

Section Z

(BUR) CRC test:
Entry point: 0xC009, CRC test fails, internal CRC is wrong, no crossrefs to this function in code. Test checks ROM area from $C100 to $FFFF and goes to infinite loop with message "CHECK SUM ERR" or just exit procedure quietly. Cartridge version of this game based on FDS version. There is still almost 1K or FDS system bios contains in NES ROM at the same location. Some parts of code designed the same way it was in FDS version, but with some modifications. The same routine, but slightly different, present at start of FDS code and perform test of three address locations quietly, tests are pass so game goes further without any messages. Looks like this routine was planned for cart version too but not included in final version for some reason.

There is some hidden text in two 16K CHR ROM blocks just before numbers graphics: "I love M.Akakura", "Madwoman Megumi". Each block is according to one game graphics pack switchable by cheat above. Another HUDSON's games contain some secret messages about "KIKU" and "MEGU". "KIKU" stands for Kikuta Masaaki (菊田政昭) but "MEGU" was still unknown. It seems there was some woman programmer in HUDSON. Both messages from "Star Soldier" means woman with name starting with "M". What if this is the same woman names? M.Akakura and Megumi must be same person just in both good and bad moods. ;) So we have probably name of beloved woman programmer - Megumi Akakura.

Ultimate Stuntman

14 people version:

(BUR) GameGenie:
Absolutely all games by Codemasters have internal PRG ROM and CHR RAM testing routines. They called "Smiley tests". Tests are normally enabled, but for triggering it needs pressing all D-pad buttons. For performing PRG ROM test it needs to hold Up + Down + Left + Right + A + Select + Start. For performing CHR RAM test it needs to hold Up + Down + Left + Right + B + Select + Start. Without controller modification it is impossible. GameGenie codes allows you to do not use D-pad buttons for triggering cheat, only A + Select + Start and B + Select + Start. But it affects on ROM's CRC. I ran these tests normally by cheating with debugger, so I wrote normal CRC tests results in brackets.
